Existence and Uniqueness for Double-Phase Poisson Equations with Variable Growth

Mohamed Khamsi, Osvaldo Mendez

We study a class of nonlinear elliptic problems driven by a double-phase operator with variable exponents, arising in the modeling of heterogeneous materials undergoing phase trans…

The Dirichlet problem for the $p (x)$ -Laplacian with unbounded exponent $p (x)$

M. Khamsi, J. Lang, O. Mendez +1

We prove the solvability of the Dirichlet problem for the variable exponent $p$ -Laplacian with boundary data in $W^{1, p (x)} (Ω)$ on a bounded, smooth domain $Ω \subset R^{n}$ …
